The I 100 is built for scale. With a Total Length (L) of 228 mm, it is nearly a quarter-meter long, providing the mass and surface area required to stabilize high-horsepower drives.
Extracted from the dimensional table for the I 100 configuration:
| Specification | Metric Value |
| Max Bore Capacity (d1 / d2) | 38 / 100 mm |
| Outer Diameter (D) | 210 mm |
| Hub Outer Diameter (D1) | 152 mm |
| Total Length (L) | 228 mm |
| Sleeve Length (L1) | 102 mm |
| Standard Hub Length (l1 / l2) | 110 mm |
| Space Between Hubs (l3) | 8 mm |
| No. of Teeth | 48 |
The I 100 introduces design refinements necessary for managing the extreme forces found in utility-scale machinery:
Deep Shaft Engagement: The hub length ($l1/l2$) is 110 mm. This allows for a very deep seat on the motor and driven shafts, which is critical for preventing "fretting corrosion" and ensuring the keyway can handle massive starting torques without shearing.
Expanded Axial Clearance ($l3$): The gap between hubs increases to 8 mm. In the large-scale pumps and compressors where the I 100 is typically used, shafts can experience significant thermal expansion. This 8 mm gap provides the necessary "breathing room" to prevent axial loading on the motor bearings.
High-Torque Hub ($D1$): The Hub Outer Diameter reaches 152 mm. This massive amount of steel surrounding the bore ensures that the coupling remains rigid and true even under the stress of 100 mm shafting.
48-Tooth Precision: Despite its size, the 48-tooth count ensures that torque is distributed extremely evenly across the large elastomeric element, providing excellent shock absorption for high-inertia loads.
| Feature | I 80 | I 100 | Change |
| Max Bore | 90 mm | 100 mm | +10 mm |
| Total Length (L) | 186 mm | 228 mm | +42 mm |
| Outer Dia (D) | 178 mm | 210 mm | +32 mm |
| Gap ($l3$) | 6 mm | 8 mm | +2 mm |
Utility-Scale Wastewater Pumps: Driving high-head pumps that move millions of gallons daily.
Large Industrial Compressors: Used in air separation plants or large-scale refrigeration.
Mining & Aggregate: Driving heavy-duty crushers or long-distance overland conveyors.
Large Marine Auxiliaries: Used for fire pumps or ballast systems on large vessels.
Summary
The I 100 is a massive coupling for massive tasks. It bridges the gap between standard industrial drives and the absolute largest size in the series, the I 125.
